Definitions

  • This invention relates generally to the field of motor vehicle frames, and more specifically to the hydroforming of hollow parts for use in motor vehicle frames.
  • hydroforming hollow parts is that high-strength parts having irregular cross-sectional configurations can be made easily and cost-effectively, in a manner which would be extremely difficult if not impossible to accomplish using stamping or roll-forming techniques.
  • the cross-section diameter of the uniform cross-sectioned blank typically cylindrical in shape
  • the blank is then expanded as determined by the size of the die cavity. Where portions of the tube blank are to be expanded to very large extents (e.g., greater than 30%), the wall thickness of the tube at such locations may become overly thin to the detriment of the part.
  • a method for securing a fastener connecting sleeve into a pre-fabricated hollow member comprises inserting the connecting sleeve into the interior of the hollow member through one end of the hollow member so that the connecting sleeve has its first and second opposing open ends disposed adjacent to the first and second walls of the hollow member.
  • the first wall is then deformed to form a first flange that surrounds the first hole and projects into the first open end of the connecting sleeve.
  • FIG. 3 is a sectional view of the hollow member having been expanded in the hydroforming cavity in accordance with the invention
  • FIG. 4 is sectional view of a generally conical tubular blank in a hydroforming cavity in accordance with another embodiment of the invention
  • the first of the two hollow members 10 has a first open end 14 with a predetermined structural dimension and shape and a second open end 15.
  • the second of the two hollow members 12 also has a first open end 16 with a predetermined structural dimension and shape and a second open end 17.
  • One or both of the dimension and shape of the first end 16 of the second hollow member 12 differ from that of the first end 14 of the first hollow member 10.
  • the two hollow members 10. 12 may be of any metallic material and may be formed in any manner appropriate to the material and desired application, but most preferably extruded, and preferably made from aluminum.
  • the members 10, 12 preferably have a multi-sided, non-cylindrical cross-section shape (e.g., triangular, quadrilateral, pentagonal).
  • a third hollow member 18 which acts as an adapter or transition member is formed which has a first open end 20 with generally the same structural dimension and shape as that of the first end 14 of the first hollow member 10, and which also has a second open end 22 with generally the same structural dimension and shape as that of the first end 16 of the second hollow member 12.
  • Shown schematically in FIG. 1 are the weld lines 24 used to connect the third hollow member 18 to the first and second hollow members 10, 12.
  • the adapter 18 is formed by hydroforming. More particularly, referring now to FIGs. 2 and 3, a tubular metal blank 30 is hydroformed into a component having differing transverse (cross-sectional) dimensions and/or shapes at the opposite ends 20, 22 thereof. As shown in FIG.
